Thanks for having a little patience with me and helping me get this DNS set up
correctly.

This is my pri.32-28.178.175.216.in-addr.arpa on my master nameserver
(fsn1.frontstreetnetworks.net)
Is there somethning wrong with it? I dont have 32, 33, or 47 in the file
32 of course is the network.
33 is the sDSL gateway
47 of course is the broadcast address.
fsnxn.com are not registered domain names, just placeholders for the IP? (maybe
questionable practive)
